SLED-PROPELLER;

SPECIFICATION forming part of Letters Patent No. 282,302, dated July 81,1883.

Application filed October 28J1882. (No model.)

ters on the drawings representinglike parts.

In a sled embodying my'improvements I employ means for supporting androtating the propeller of such character that the latter, resting bygravity upon the snow or road-bed covered more or less by it, may alwaysbe free to rise and fall according to the irregularities of the snow androad-bed, such sled being provided with spring stops or brakes andsteering-levers,*which are combined with cranks and levers adapted to beoperated by the foot of the rider of the sled.

Myinvention consists in mechanical organizations, as hereinbefore morefully set forth, and claimed at the end of'this specification.

Figure 1 is a side elevation of a sled embodying my invention, and Fig.2 a top or plan View thereof. 1

The framework A, runners a, and standards a of the sled may be of anyusual or suitable shape and material. The sled has an elevated seat, b,at each side of which are like actuating-levers, b, pivoted at If, andjoined by connecting-rods b with oppositely-arranged cranks b of theshaft of the propeller c, the

said shaft having its bearingslinside its eranh s in boxes secured to aframe, (2, hinged or pivoted to the sled-frame at d, so that the spokesor blades of the propeller, preferably made wedge-shaped at their outerends and shod with metal pieces to insure durability, may rest upon thesnow at the rear of the sled, and the propeller be free to rise and fallto adapt itself to the irregularities of the snow or road-bed covered byit as the propeller is rotated by the actuating-levers b, shown asadapted to be operated byhand. At each side of the sled is a likesteering-lever, g, pivoted at g, and connected at its forward end withan arm, 6, of a rock-shaft, e, having a second arm or foot-piece, 9against which the foot of the rider maybe pushed to cause the rear endof the steering-lever to be thrown down in contact with the snow orroad-bed at the rear of Either one or the other steeringthe runner.lever may be operated at will to direct the course of the sled. The rearend of each steering-lever is normally kept elevated by a suitablespring, h, the latter also serving to keep the arms 9 normally turnedtoward the seat I).

To stop thesled, I have providedthe standards at opposite sides of thesled with ears m,

(shown in dotted lines,) to receive the legs of a stopping device, mshaped as a large staple, and having its cross bar or head exposed tothe foot of the operator through a slot in the board or top A of thesled. Each leg of the stopping device has aeollar, m, and below the saidcollar and the lower ear, m, is a spiral spring, in, which normally actsto keep the stopping device elevated, as herein shown in Fig- 1. Thestopping device may be pressed down into the snow or ice or earth belowthem and stop the sled.

1. A sled provided with propelling mechanism, spring-supported stoppingdevices m, guiding or steering levers g, and arms 6, rockshaft 6, andfoot-piece y to operate substantially as shown and described.

2. The spring-supported stopping device m, applied to a sled, andconstructed and an ranged substantially as shown and described. 3. Theguiding or steering levers 9, combined with the arms 0, rock-shaft e,and foot-piece Witnesses:
